A Texas man accused of helping a lottery security official try to claim a rigged $14 million jackpot is scheduled to appear in court Thursday.

Robert Rhodes is expected to contest his extradition to Iowa during the hearing in Texas.

The Sugar Land businessman was arrested in March and is free on bond. Prosecutors say he worked with an Iowa friend, Eddie Tipton, and others in an attempt to claim the Hot Lotto jackpot that Tipton had rigged.

Tipton was security director for the Multi-State Lottery Association, which operates Powerball.

Prosecutors allege that Tipton inserted a software program into the random number generator for Hot Lotto that allowed him to manipulate the winning combination.
